Let us assume f(x) = 2x - 5
f⁻¹(x) = (x + 5)/2
f(f⁻¹(x)) = 2((x + 5)/2) - 5 = x
f⁻¹(f(x)) = (2x - 5 + 5)/2 = x
The domain of a function is the range of its inverse and vice versa
The range of a function is the domain of its inverse and vice versa
Therefore, statements A, B, D and E are true
Answer:
atoms
Explanation:
All matter is made of elementary particles called "atoms".
Answer:
Stellar Spectra Classification The patterns of lines detected in stellar spectra are used by astronomers to classify stars into spectral classes. These spectral classes are a measure of a star's surface temperature since the temperature of a star dictates which absorption lines are present in its spectrum.
Explanation:
Answer:
The time constant τ = L/R represent the time requiered for the curent to get value of 63 % of its maximun value
Explanation:
In a circuit RL ( serie circuit with a resistor R and the inductor L ) when a voltage is applied the inductor will have a reaction, such reaction consist in the creation of an electromotive force which will prevent the current to get its maximun value. The time constant which in the case of an inductor is
τ = L/R , represent the time requiered for the crrent to be 63 % of its final value
